摘要
提出了一种基于光纤马赫 曾德尔干涉仪和取样光纤光栅的新型全光纤梳状滤波器。通过对器件的工作原理的理论分析 ,发现耦合器的分束比、取样光纤光栅的光谱特性和干涉臂长差是决定这种全光纤梳状滤波器性能的三个主要因素。并对器件性能进行了模拟计算。实验上获得了信道间隔为 1 0 0GHz的初步实验结果。
A novel all-fiber interleave filter using Mach-Zehnder-based sampled fiber gratings was proposed and fabricated. The operation principle of this device was introduced, and its performances were analyzed mathematically. In this proposed interleaver, the splitter ratio of coupler, the spectrum of sampled fiber grating and path-length difference of two arms are the three key parameters that determinate the performances of the interleaver. The interleave demonstrates channel spacing of 100 GHz.
